UNITED STATES EDWARD BITTEL, OF FOREST PARK, ILLINOIS.

FAUCET.

Application filed March 1, 1920.

To all 20 from it may concern Be it known that I, EDWARD BITTEL, acitizen of the United States, residing at Forest Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Faucets, of which the following is a specification.

This invention relates to improvements in faucets, and more particularlyto faucets of the type commonly known as mixing valves.

One object of the invention is to provide a device of this characterwhich shall be extremely simple in construction and operation, andeconomical to manufacture, while at the same time providing forefficient and positive actuation, and retaining all the other advantagesof the more expensive mixing valves now in common use.

' Other objects and advantages of the invention will become apparentfrom the following specification when read in the light of theaccompanying drawings, wherein one form of the invention is illustrated.

Figure 1 is a sectional view, taken through a mixing valve constructedin accordance with the present invention;

Fig. 2 is a sectional view, taken on the line 22 of Fig. 1; and

Fig. 3 is an elevation of thevalve member and its operating stem, themixing chamber being shown in dotted lines, in order to illustrate moreclearly the mechanism whereby longitudinal movement is imparted to thevalve member upon each rotative movement thereof.

Referring more in detail to the drawings, the faucet or mixing valve isdesignated in its entirety as 10, and comprises a. cylindrical mixingchamber 11, having a centrally disposed outlet 12 in one end wallthereof, this outlet terminating in a laterally disposed dischargenozzle 13. The mixing chamber is also provided with a plurality oflateral inlets 14c and 15, which communicate with the interior of thechamber through the side wall thereof. Mounted within the mixing chamber11 on an operating stem 16 is a piston-like valve member 17, ofsubstantially the same diameter as the interior diameter of said chamberand having suitable openings 17 therein. This valve member is providedwith a rearwardly extending flange 17, of a contour corresponding tothat of the inner surface of the chamber and closely fitting against thelatter. This Serial No. 362,330.

flange is designed to close the inlet openings 1 1 and 15, as shown moreclearly in Fig. 2 of the drawings. A valve seat in the form of a leathergasket, or the like 17, is carried on the front face of the valve member17 and surrounds the operating stem 16, this valve seat being designedto close the outlet 12 of the faucet when the valve member is in itsnormal position, as shown in Fig. 1. As will be observed, the operatingstem extends centrally through the outlet 12 and the mixing chamber 11,said stem being provided with an operating grip or handle 16 At thepoint where the stem projects through the casing of the faucet asuitablescrewthrcaded cap 18 and packing 18 are pro vided, in order to preventleakage. The valve member 17 slidably and rotatably mounted in themixing chamber, and, as will be observed, upon rotation of this memberthe rearwardly projecting flange 17 will be moved in one direction orthe other to uncover one of the inlet openings 1 1 or 15. A cam recess17 is provided in the front face of the valve member, and extends for ashort distance along its outer periphery. This cam recess is designed toreceive the cam 19 provided on the inner adjacent face of the end plateof the mixing chamber.

From this construction it will he observed that upon rotation of thevalve member 17 to uncover or open either of the inlets 1 1 or 15, saidvalve member will be simultaneously moved longitudinally within thechamber 11 away from the outlet end thereof, thus uncovering the outlet12 and providing a direct passage from the open inlet through apertures17 of valve 17 to the discharge nozzle 13. The cam 19, being carried bythe end plate of the mixing chamber, is, of course, stationary, and assoon as the valve member 17 is rotated said member is caused to ride upupon the cam, thereby imparting to the valve member a longitudinalmovement within the mixing chamber simultaneously with the rotarymovement imparted thereto through the operating stem 16. As soon as itis desired to out off communication between the inlet which has beenopened and the discharge nozzle, it is merely necessary to rotate thestem 16 until the cam recess in the face of the valve member has beenbrought into cooperative relation with respect to the cam, whereupon thevalve member will be automatically returned to its normal closedposition through the agency of the coil spring 20, which, as will beobserved, is interposed between the rear face of the valve member andthe adjacent end wall of the mixing chamber 11. I

In order to permit the stem 16to reciprocate back and forth with thevalve member 17 as the latter is operated to open or close communicationbetween the outlet and one or the other of the inlets, the end wall ofthe chamber 11, against which the spring 20 seats, is provided with arearwardly projecting, centrally disposed socket 21', adapted to receivethe inner end of the stem 16. In this manner longitudinal movements ofthe stem are permitted, while at the same time a guide is provided forthe rear end of the stem. The forward portion of the stem is guided bythe cap 18 at its point of projection through the casing of the valve.

As will, be readily appreciated, one of the inlets is for connectionwith a suitable cold water supply, while the other member may beconnected with a supply of hot water, so that by turning the valvemember 17 in one direction cold water may be obtained, while a turningthereof in the opposite direction will close the cold water inlet andopen the hot water inlet. hen it is desired to obtain a mixture of bothhot and cold water through the discharge nozzle,the valve member 17 isrotatedin either direction a sufficient distance to fully uncover oropen both inlets; or, if desired, the mixture may be regulated to anydegree by fully uncovering or opening one or the other of the inlets,and only partly opening the other. In this manner a mixture of hot andcold water of any desired temperature may be obtained.

While the valve member 17 has been shown as formed integrally with theoperating stem 16, it will of course be appreciated that said member maybe formed separately and attached by a key, or otherwise, to the stem,so that it may be moved longitudinally on the stem upon rotation of thelatter.

It will also be obvious to'those skilled in the art that the presentimprovements are susceptible of changes and modification, andaccordingly it is not desired to limit the invention to the particularconstruction and details herein described and illustrated, except asdefined in the appended claims.

I claim l 1. In a device of the class described, a cylindrical mixingchamber, an outlet at one end thereof, a plurality of laterally disposedinlets, a piston-like valve member normally closing both of said inletsand said outlet, means for rotating said valve member to un cover one orboth of said inlets, means for simultaneously moving said valve memberlongitudinally within said cylinder to open said outlet, and means forautomatically returning said valve member to its normal closed positionwhen said last named means is in operative position. v

2. In a faucet of the type described, a cylindrical mixing chamber, anoutlet in one end wall thereof, laterally arranged inlets in the sidewall of said chamber, a circular plate slidably and rotatably mountedWithin said chamber and provided with a rearwardly projecting flangeadapted to close said inlets, means also carried by said plate forclosing said outlet, said plate being provided with a cam seat formed inone of its faces, and a stationary cam designed for coopera tion withsaid seat whereby upon rotationof said plate to open either or both ofsaid inlets said. plate will also be moved longitudinally within saidcylinder to thereby open said outlet.

A mixing valve comprising a cylindrical chamber, an outlet and aplurality of inlets therefor, a piston-like valve member in the form ofa plate slidably and rotatably mounted within said chamber, the frontface of said plate normally closing said outlet, a rearwardly projectingflange on the rear face of said plate adapted to normally close saidinlets, means for rotating said valve to open either or both of saidinlets, and a stationary cam mounted within said cham ber and engagingsaid plate for moving the latter rearwardly to uncover said outletsimultaneously with the opening of said inlets.

In testimony whereof, I havesubscribed my name.
